Try cleaning the contacts in the cartridge holder with some isoproyl alcohol on a q-tip. If that still does not work, then try reinstalling the driver after uninstalling it first. Should the issue still continue, then it indicates a sensor problem, for which servicing will be required.

Hope that helps!

Check ur tv fan,if ur cooling fan are runnig,before all these LED lights are flashing.If not that ur tv problems.All these LED lights are flashing the tv making alots of clinking noises too like it trying turn itself on?Yes,than the tv board that called the Ballast board it is dead too,must be replace also.This tv Ballast board only job are to help to ignite the tv projection lamp only and keeping it on and running.

Flashing green standby led light at the front panel is an indication that the unit waiting for the lamp to turn on. Since the lamp led light flashes, the unit sensed it already burned out.
Faulty lamp driver has a different error code which is "flashing of the standby light 5 times".
Your unit will back to normal operation again after the lamp replacement.

1. Red status LED, self-diagnosis error 44,

Disconnecting the USB connector from the Card Reader did not help. Remove
connector FC from the FMT PCB and plug the unit in, if the LED stops blinking

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note: The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.
